2/5(5x-3) - 1/3(12x-5). Have the correct answer but need someone to show me how to solve for it.

  • college algebra - ,

    2x-6/5 - 4x+5/3

    -2x +1/15 (-6+25)
    -2x+ 19/15

    Amber, I'm not sure if my solution is correct but I will take a stab at it.

    Your problem was:
    2/5(5x-3)-1/3(12x-5)
    2x-6/5-4x+5/3
    -2x-18/15+25/15
    -2x+7/15

  • college algebra - ,

    You made a mistake bobpursley in solving Amber's problem.

    6/5 does NOT equal 6/15! 6/5=18/15 Therefore your calculation in line 2 of your solution is incorrect!
    It SHOULD read:
    -2x+1/15(-18+25)
    -2x+7/15

    Thanks. I see that. You are correct.

    2/5(5x-3) - 1/3(12x-5)
    10x/5-3/1(5/5) -12x/3 +5/1(3/3)
    2x-3 -4x +5
    2x-4x - 3+5
    -2x + 2
